REFRIGERATOR.

Appiieaiion ined May 21,

My invention relates to refrigerators and has for its object to providea refrigerator, the entire interior` of which may bc enameled to form aperfectly sanitary construction.

Another object of the invention is to provide a device for preventingthe walls of the ice chamber adjacent the food .compartment fromsweating and causing moisture to drip l0 from the same.

Another object is to provide a separate food compartment and ice chamberwith enameled interior surfaces and to mount the same with their wallsin spaced relation to one another to form a sweat proof and sani taryconstruction.

Heretofore it has been practically impossible to construct arefrigerator in which the entire interior including the ice chamber andfood compartment have been formed of enameled iron due to the sweatingoccasioned within the food chamber. In my invention I have overcome thisby forming the lining in separable portions so as to provide the entirewalls surrounding the ice chamber of double thickness with some suitable insulating material such as an air space, wood or the like,interposed between the same in order that the traiisfei of heat from theouter to the inner wall of the ice chamber by conduction is prevented.

The full objects and advantages of my invention will appear in`connection with the detailed description thereof and are particularlypointed out in the claims. l

In the drawings, illustrating the application of my invention in oneform:- Fig. 1 is a front elevational sectional view of a refrigeratorshowing my invention applied thereto. i

Fig. 2is a side sectional view similarto Figure 1 of a modification oftheinvention shown in Figure 1.

Fig. 8 is a fragmentary sectional view similar toFig. 1 Of amodification of the invention shown in Figure l.

In Figures l and 2, I have shown' a re frigerator formed with an outercasing A having a top10, side walls 11 and 12, a bottom 13, a front laand a back 32. These walls may be of any suitable construction forinsulating and supporting the interior of the refrigerator. The frontwall 14E of casing A is provided with openings25 and 26 by means ofwhich access is had into the 1921. Serial No. 471,352.

interior of the refrigerator. These openv ings may be closed by suitableclosure inembers or doors 2'? and 28 adapted to close tight over theopenings 25 and 26 and to insulate the interior of the refrigerator fromthe exterior.

Within the interior of the refrigerator is provided two separate liningsor shells B and C, which are arranged in relation to one another as bestshown in Figure 1. Shell C is substantially L shaped and is providedwith a short top 15 positioned adjacent the casing member 107 a bottom1G positioned on the casing member 13, and a member 17 which runsparallel with the bottom 16 and 70 which in conjunction with the portionof the bottom 16 forms the lower leg of the L. Shell C is furtherprovided with a side member 18 which lies against the side wall 11 andwith an upstanding side member 19 75 which in conjunction with the upperpor tion of the side 18 forms stem of the L. An end wall 20 positionedadjacent wall 12 of the casing A encloses the end of the leg of the L.At the rear of shell C the Same is formed with a back 21 which is of Lshaped formation and at its front with a similarly formed L shaped frontmember 22 which is provided with openings 211 to register with theopenings Q6 in the 'front 14 85 of the casing A.

In the angle of the L shaped shell C is positioned the shell B which isof rectangular shape having a top 29 and an end wall 30 lying adjacentthe walls 10 and 12 of 90 the casing A and having a back 31 and a front33 situated adjacent the bacliwall 32 and front wall let of said casing.This front wall 33 is formed with an opening 23 adapted to register withthe opening 25 in g5 the front wall 1.4L of casing A as is clearly shownin Figure 2, whereby access may be had into the ice compartment of therefrigerator. Shell B is further provided with `a side wall 34:positioned parallel to the side 100 wall 19 of shell C and with thebottom 35 positioned above the top wall 1'? of said saine shell C.

In the foi-m of thev invention shown in Figures 1 and 2 the shell Bforming the ice 105 chamber is made of such -a shape and size that whenthe same is positioned within the refrigerator casing A the walls 19 and34 and the top and bottoni members 17 and 35 of said shells arepositioned in spaced relaridge to opening.

tion to one another as clearly shown in Figure l. For holding shellmembers B and C in proper relation to one another within therefrigerator easing A the space between the walls i9 and 34 and betweenthe top 35 and bottom of said shell members may be filled with a wood orother insulating member 36 which extends within the same and which maycompletely or partially llill the space as desired. o

' To provide a passageway for the circulation of the air within therefrigerator l form an opening 37 i-n thesidewalls i9 and 3'4 of shellmembers C and B which vopening extends completely across therefrigerator and is positioned immediately below thetops 155 and 29thereof. This opening is formed by turning over allange 38 on the metalof the side' 19 which engages a corresponding i fla/nge 39 formeel onthe wall 34and adapted to cooperate therewith to form a closed wallextending perimetrically aroundY said open ing`37. In a simil-ar mannerthe top i7 and bottom 35 are provided withan` opening 42 which is formedby an upstanding continuous 'flange 40v adaptedV to cooperate with acorresponding turned over lip or flange 4l formed on thel bottom member35. rilo prevent the Water of liquefaction of the ice fromY dischargingthrough the opening 42 into. the food compartment i preferably7 formthelip 41 which extends completely around; this opening raised above theplane olf" the surface/of bottomi 35 so aste form a prevent the overflowthrough said Y For the-purpose of draining the ice chamber of water lpreferably slopeA the bott-om member 3-5-of shellB towards the frontwall 33 and'lside Wall 34 of said shell. At the lowest point of thisbottom 351 provide a discharge pipev 43 passing through the insulatingmember 35 and the top 17 of shelly Cf This discharge pipe may beconnected by af tube 44 to any suitable trap 45 byineans ofv which theWater may escape from the refrigerator through a discharge pipe 46.Thetrap* 45-has`not been shownin detail in the-drawings though-it canbei-'clearly understood that any suitable form of trap adapted torefrigerators may be used for this purpose. Y

" In Figure `3 lhave shown a slight variation in the formv ofrefrigerator shown in Figure l. In this type the insulating medium 36shown in Figure l is dispensed Vwith and a number of spacers 47 employedwhich areattachedto the side walls V19 and 34 andthe top 17 and bottomV35-of members (C and'B, to hold the same in proper relation to oneanother. With this construction an air space 48 is' provided which maybe continuous or'interrupted depending upon the size and;- formatlionof'thespacermember 47.

TheA exact' .formation ofV this air space,v howrenier ever, isunimportant as far as the functioning of the parts is concerned.

in both of the iorms olf my invention shown in the drawings l prefer tocoat the interiors of both the food compartment and ice chamber withenamel to make the refrig crater perfectly clean and sanitary, It can bereadily understood that this coating of enamel can be baked on orapplied by any of the ordinary methods now .in use. in this way theinside of each of the containers is enameled and the parts so arrangedthat the corresponding unfinished exterior surfaces of the same arecompletely hidden from view so as to expose nothing but the cleanenamel.

rlhef advantages of my invention are manifest. Y yThe two compartmentscan be indeaendentlVT constructed and enameled on the .i

interior of the same as if a single container were used. in this mannerthe construction of tie device is still held exceedingly simple' and theparts prepared in the usual manner. After the same have been enameledthe parts are assembled with the walls thereof in spaced relation to oneanother. in this manner all of the unfinished surfaces are hi dden andthe walls` adjacent the ice chamber are insulated from the foodcompartment sor that sweating on the interior walls of the foodcompartment is eliminated. ln this manner an exceedingly clean andsiianitary refrigerator is provided in which sweating is entirelyeliminated.

in accordance withl the patent statutes l have described the principlesof operationr of my invention, together with the apparatus which I nowconsider to' represent the best embodiment thereofybut I. desire'tohaveit understood that the construction shown is only illustrative and thatthe inventioncan be carried out by other means and applied to usesotherthan those above set forth within the scope of the following claimsl.
